Recoil starter for backpack-type power working machine

Abstract

A starter which is capable of having an operator easily perform the starting operation of a backpack-type power working machine while shouldering it, is lighter in weight and cheaper in manufacturing cost, is relatively free from trouble, and can not easily be damaged even if a portion of the starter is caught by the branch of a tree. In this starter, a recoil handle attached to one end portion of the recoil rope is placed remote from the main body of the starter by a predetermined distance and adapted to be supported by a handle-supporting member provided at a specific portion of the working machine; and an extended portion of the recoil rope which is located between the main body and the handle-supporting member is loosely sheathed by a flexible guide pipe, one end of which being fixed, and the other end being made free.

What is claimed is:  
     
       1. A recoil starter for starting an internal combustion engine to be mounted on a backpack-type power working machine, the recoil starter comprising: 
       a main body;  
       a recoil rope extending from the main body;  
       a recoil handle attached to an end portion of the recoil rope, placed remote from the main body of the starter by a predetermined distance, and adapted to be supported by a handle-supporting member provided at a specific portion of the shoulder-type power working machine; and  
       a flexible guide pipe loosely sheathing an extended portion of the recoil rope located between the main body and the handle-supporting member, a first end of the guide pipe being fixed and a second end of the guide pipe being free;  
       wherein the handle-supporting member is provided at a portion of the working machine approximately corresponding to the waist portion of an operator shouldering the working machine, thereby enabling the recoil handle to be pulled toward the front of the operator on the occasion of starting the internal combustion engine.  
     
     
       2. The recoil starter according to  claim 1 , wherein the guide pipe is made of a synthetic resin. 
     
     
       3. The recoil starter according to  claim 2 , wherein an elastic ring member is externally fitted on the second end portion of the guide pipe located close to the main body. 
     
     
       4. The recoil starter according to  claim 1 , wherein an elastic ring member is externally fitted on the second end portion of the guide pipe located close to the main body. 
     
     
       5. A shoulder-type power working machine comprising: 
       a backpack frame;  
       a power source mounted on the backpack frame;  
       a blower connected to the power source and mounted on the backpack frame;  
       a recoil starter coupled to the power source; and  
       a handle-supporting member coupled to the backpack frame;  
       the recoil starter further comprising:  
       a main body;  
       a recoil rope extending from the main body;  
       a recoil handle attached to an end portion of the recoil rope, placed remote from the main body of the starter by a predetermined distance, and adapted to be supported by the handle-supporting member provided at a specific portion of the backpack-type power working machine; and  
       a flexible guide pipe loosely sheathing an extended portion of the recoil rope located between the main body and the handle-supporting member, a first end of the guide pipe being fixed and a second end of the guide pipe being free;  
       wherein the handle-supporting member is provided at a portion of the working machine approximately corresponding to the waist portion of an operator shouldering the working machine, thereby enabling the recoil handle to be pulled toward the front of the operator on the occasion of starting the internal combustion engine.  
     
     
       6. The backpack-type power working machine according to  claim 5 , wherein the guide pipe is made of a synthetic resin. 
     
     
       7. The backpack-type power working machine according to  claim 6 , wherein an elastic ring member is externally fitted on the second end portion of the guide pipe located close to the main body. 
     
     
       8. The backpack-type power working machine according to  claim 5 , wherein the guide pipe is made of a synthetic resin. 
     
     
       9. The backpack-type power working machine according to  claim 8 , wherein an elastic ring member is externally fitted on the second end portion of the guide pipe located close to the main body. 
     
     
       10. A shoulder-type power working machine comprising: 
       a backpack frame;  
       a power source mounted on the backpack frame;  
       a blower connected to the power source and mounted on the backpack frame;  
       a recoil starter coupled to the power source; and  
       a handle-supporting member coupled to the backpack frame;  
       the recoil starter further comprising:  
       a main body;  
       a recoil rope extending from the main body;  
       a recoil handle attached to an end portion of the recoil rope, placed remote from the main body of the starter by a predetermined distance, and adapted to be supported by the handle-supporting member provided at a specific portion of the backpack-type power working machine; and  
       a flexible guide pipe loosely sheathing an extended portion of the recoil rope located between the main body and the handle-supporting member, a first end of the guide pipe being fixed and a second end of the guide pipe being free;  
       wherein an elastic ring member is externally fitted on the second end portion of the guide pipe located close to the main body.  
     
     
       11. The backpack-type power working machine according to  claim 5 , wherein an elastic ring member is externally fitted on the second end portion of the guide pipe located close to the main body. 
     
     
       12. The backpack-type power working machine according to  claim 10 , wherein the guide pipe is made of synthetic resin.
